I too have a fresh install of 5.4+ and cannot add a page. I have been working on this all day, since I thought I was doing something wrong. All I get after setting up the parameters of the page and clicking the add button, is an image of a static circle. Please, I hope someone has an answer soon.

Check the web server error logs to confirm that the installation completed without errors. Look for any errors after an attempt to add a page. Look at the Concrete5 logs to see if there are any errors. Are there any errors in the web page?

These are common debugging techniques that every website owner/designer goes through when there is a problem. You are the best person to troubleshoot your system, because you are right there, and you know your way around. If you can't track down the problem, the more details you provide, the better quality answer you will receive.

no errors in the log (server and c5), and on 3 different hosts, and no errors on the page,

Believe me i checked

I have tried un-installing and re-installing but have not had any different results.

Is there anything in the web page if you view the source? Is there anything else that is not working correctly? I assume that you checked all of the other normal things.

1. Flushed the cache on your browser.
2. Tried a different browser.
3. Have sufficient disk space.
4. Have sufficient table space in the database.
5. All files and directories have the correct permissions.

Can the admin user add a new page?

1. Remove the Administrators group from the parent page.
2. Save the changes.
3. Add the Administrators group to the parent page with all of the permissions.
4. Don't forget to specify the sub-page permissions, or the "Add Page" icon won't show up in the edit bar.
5. Save the changes.

1. Done
2. Done
3. Yes
4. Yes
5. Yes

1-5 Nope

:(

Is there any content in the web page if you view source?

That's why one of my points above is "Don't forget to specify the sub-page permissions".

I am glad Mnkras found the problem. When I click on set permissions I see only a simple page for who can view and who can edit. I do not have a place to click to see sub pages and all the detail. Any suggestions?
Added later: I found instructions to add <?php define('PERMISSIONS_MODEL', 'advanced'); ?>
to the config/site.php. I think all in all everything is running smoother today than yesterday. Also, I am working on my site directly through IE8 browser. Yesterday I was working through MSN which might have had an impact.

Just wanted to say that I also ran into this issue after one of our admins was trying to create a custom login page. Your solution worked. Thank you for that screencast!

Thanks a ton!! Saved me a lot of time!!

Thanks for the pointer ... surprised I never came across this problem before ... I wonder if it only happens if advanced permissions model is set in config?

Had the exact same problem. Found the asnwer here:http://www.concrete5.org/community/forums/usage/administrators-cann...
